The largest single-phase hybrid configuration. 18 LONGi panels on a Solis 10kW inverter (11.7kW DC) delivers 1,350–1,650 units/month — enough for a large kothi running 3 ACs or a small commercial establishment. Full-package price with 6mm² AC cabling.
An 18-panel system on a Solis 10kW hybrid inverter is Saigal Solar's Large Home Package — one step above the Family Package. At 11.7kW DC, this fills the inverter close to its maximum and maximises summer generation. It is also the practical ceiling for single-phase residential solar in Pakistan.

⚡ Open the Solar Design Tool — FreeThe Solis S6-EH1P 10kW is the largest single-phase hybrid inverter in our range. It accepts up to 20kW of DC input, so 18 panels (11.7kW DC) is well within capacity. There is no single-phase 12kW hybrid inverter available from Solis or GoodWe in Pakistan — using 18 panels on a 10kW inverter is the correct engineering approach. The inverter clips slightly at peak (when all 18 panels produce simultaneously), but overall energy harvest over a full day is comparable to a true 12kW inverter.
Yes. 18 panels exceed the single-trip limit (14 panels = 1 trip, above 14 = 2 trips). Two Suzuki Ravi vehicles are required to transport 18 panels safely without bending or overloading. Both transport trips (Rs. 14,000 total) are included in all prices shown on this page. This is a real cost that some installers omit from their quotes — always ask about transport.
Net metering policy in Pakistan has changed in 2026. NEPRA announced the cancellation of the traditional net metering programme. Under current rules, excess energy exported to the grid is not credited at retail rates. For a 12kW system, this means sizing the system to match your daytime load rather than oversizing to export. We recommend 18 panels for a 12kW system as this balances generation and self-consumption correctly.
An 18-panel system typically takes 2 days in Faisalabad. Day 1 covers GI structure assembly, panel mounting on the roof, and cable runs (DC wiring from roof to inverter room). Day 2 covers inverter installation, DB box work (MCBs, changeovers), battery connection, 3-pit earthing (DC, AC, lightning), testing, and commissioning with app setup. We clean up after installation and provide a handover walkthrough.
